Foam roller for yoga

Abstract

A foam roller includes a tube and a pad. The tube is made of an elastic material and formed with an external face and an internal face. The external face of the tube includes alternately arranged facets and angles. The pad is made of a relatively soft and elastic material and formed on the external face of the tube. The pad includes facets and angles corresponding to the facets and angles of the tube.

1 . A foam roller comprising:
 a tube ( 10 ) made of an elastic material and formed with an external face ( 11 ) and an internal face ( 12 ), wherein the external face ( 11 ) of the tube ( 10 ) comprises alternately arranged facets ( 13 ) and angles; and   a pad ( 20 ) made of a relatively soft and elastic material and formed on the external face ( 11 ) of the tube ( 10 ), wherein the pad ( 20 ) comprises facets ( 21 ) and angles ( 210 ) corresponding to the facets ( 13 ) and angles of the tube ( 10 ).   
     
     
         2 . The foam roller according to  claim 1 , wherein the tube ( 10 ) comprises an internal plate ( 15 ) formed on the internal face ( 12 ), wherein the internal plate ( 15 ) extends along a central line (L 2 ) at a distance from a diameter (L 1 ) of the internal face ( 12 ) of the tube ( 10 ), wherein the distance is 0.15 to 0.70 as large as a radius of the internal face ( 12 ) of the tube ( 10 ). 
     
     
         3 . The foam roller according to  claim 1 , wherein the tube ( 10 ) comprises two open ends, wherein the pad ( 20 ) comprises two lateral covering portions ( 25 ) for covering the open ends of the tube ( 10 ). 
     
     
         4 . The foam roller according to  claim 3 , comprising two covers ( 18 ) for covering the open ends of the tube ( 10 ) to keep the material of the pad ( 20 ) out of the tube ( 10 ) during the making of the pad ( 20 ). 
     
     
         5 . A foam roller comprising:
 a tube ( 10 ) made of an elastic material and formed with a smooth cylindrical external face ( 11 ) and an internal face ( 12 ); and   a pad ( 20 ) made of a relatively soft and elastic material and formed on the external face ( 11 ) of the tube ( 10 ), wherein the pad ( 20 ) comprises a smooth cylindrical external face.   
     
     
         6 . A foam roller comprising:
 a tube ( 10 ) made of an elastic material and formed with an external face ( 11 ), an internal face ( 12 ), and internal plate ( 15 ) formed on the internal face ( 12 ), wherein the internal plate ( 15 ) extends along a central line (L 2 ) at a distance from a diameter (L 1 ) of the internal face ( 12 ) of the tube ( 10 ), wherein the distance is 0.15 to 0.70 as large as a radius of the internal face ( 12 ) of the tube ( 10 ); and   a pad ( 20 ) made of a relatively soft and elastic material and formed on the external face ( 11 ) of the tube ( 10 ).   
     
     
         7 . The foam roller according to  claim 6 , wherein the external face ( 11 ) of the tube ( 10 ) comprises alternately arranged facets ( 13 ) and angles, wherein the pad ( 20 ) comprises facets ( 21 ) and angles ( 210 ) corresponding to the facets ( 13 ) and angles of the tube ( 10 ). 
     
     
         8 . The foam roller according to  claim 6 , wherein the tube ( 10 ) comprises two open ends, wherein the pad ( 20 ) comprises two lateral covering portions ( 25 ) for covering the open ends of the tube ( 10 ). 
     
     
         9 . The foam roller according to  claim 8 , comprising two covers ( 18 ) for covering the open ends of the tube ( 10 ) to keep the material of the pad ( 20 ) out of the tube ( 10 ) during the making of the pad ( 20 ). 
     
     
         10 . The foam roller according to  claim 6 , wherein the external face ( 11 ) of the tube ( 10 ) is a smooth cylindrical external face ( 11 ), wherein the external face of the pad ( 20 ) is a smooth cylindrical external face.
